Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Form the main body and natural sweetness of the soup as they soften.
- Turnip
- Adds body and a mild, earthy flavor as it cooks down.
- Onion
- Builds a savory base flavor as it softens in the stock.
- Light-colored stock
- Provides the main liquid and carries the flavor of the vegetables and herbs.
- Arrowroot
- Thickens the soup as its starch swells when heated and boiled.
- Cream
- Adds richness and a smooth, velvety mouthfeel to the finished soup.
The step that matters
Thickening with arrowroot. Arrowroot starch thickens only when hot and stirred, and it must be smoothly blended first. Stirring as it comes to a boil keeps granules from clumping and settling, giving an even, glossy texture.
